First you have to understand the average speed is the critical component. You can get 80 MPG in a lot of cars if your average speed is 22 MPH.

Second in regards to a CVT Insight. All last summer I managed close to 80 MPG in my daily 38 mile round trip drive after warming the engine up. My best was 83 MPG one way, while averaging 40 MPH through over 40 traffic lights.

The CVT will climb very shallow grades at over 55 MPG, with acceleration that is very very gradual, measured in several seconds per MPH increase in speed, while climbing a very very slight grade, measured in a few feet per 10th mile.

Then on the very slight downgrades the instantaneous mileage will jump to 125-150 if you allow the car to very very slowly decelerate. The other traffic on the road will hardly notice the changes in speed because they are microscopic.

The best summertime mileage I got in the CVT averaging 55 MPH was 70.2 MPG for 577 miles in one day. Mostly daylight, with absolutely no accessory loads whatsoever.

I don't do engine off coasting in the Insight, not interested in wrecking a 5k transmission.
